Belief in reincarnation has been shared by a wide variety of peoples, including the ancient Egyptians and Greeks and the Aboriginal people of central Australia. The most complex and influential ideas about reincarnation are found in Asian religions, particularly Hinduism and Buddhism. Cultural groups that believe in reincarnation have different ideas about the way it takes place. Some say that human souls come from a general source of life-giving energy. Others claim that particular individuals are repeatedly reborn in their descendants.
In Australia, most Aborigines believe that human souls come from spirits left behind by ancestral beings who roamed the earth during a mythical period called the Dreamtime. The birth of a child is caused by an ancestral spirit entering a woman’s body. The spirit waits in a sacred place for the woman to pass by. After death, the person’s spirit returns to the ancestral powers.
According to traditional African belief, the souls or spirits of recently dead people linger near the grave for a time, seeking other bodies— reptile, mammal, bird, or human—to inhabit. Many African traditions link reincarnation to the worship of ancestors, who may be reborn as their own descendants or as animals associated with their clans or groups. The Zulu people of southern Africa believe that a person’s soul is reborn many times in the bodies of different animals, ranging in size from tiny insects to large elephants, before being born as a human again. The Yoruba (pronounced YAWR-uh-buh) and Edo of western Africa share the widely held notion that people are the reincarnations of their ancestors. They call boys “Father Has Returned” and girls “Mother Has Returned.”
Reincarnation plays a central role in Buddhism and Hinduism. It also appears in Jainism (pronounced JYE-niz-uhm) and Sikhism (pronounced SEE-kiz-uhm), two faiths that grew out of Hinduism and are still practiced in India. Jainism shares with Hinduism a belief in many gods. Sikhism is a monotheistic religion that emphasizes the belief in only one god. It combines some elements of Islam with Hinduism.
Hinduism, Buddhism, Jainism, and Sikhism all began in India, where the idea of rebirth first appears in texts dating from about 700 bce. They share a belief in samsara—the wheel of birth and rebirth—and karma—the idea that an individual’s actions in their current life will determine how they are reborn in their future life. People who have done good deeds and led moral lives are reborn into higher social classes; those who have not are doomed to return as members of the lower classes or as animals. Only by achieving the highest state of spiritual development can a person escape samsara altogether and enter into the state of nirvana, total union with the supreme spirit.
